DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] The gap between the wall and the column 1 is always smaller than the width of the last wall piece, which makes it impossible to insert the last wall piece horizontally between the wall and the column 1. In order to install the last wall piece of the prefabricated wall between the wall and the column 1, it is necessary to decompose the last wall piece into multiple modules so that it can be spliced ​​into one piece along the thickness direction of the wall.

[0041] The following provides a three-way plug-in assembled wall, which includes: a first base 2, a first sheet 31 and a second sheet 32;

[0042] The first base body 2 is in the shape of a flat plate. A first splicing portion 21 is formed on at least one side of the first base body 2. The first splicing portion 21 is protruding or recessed along the width direction of the first base body 2. The thickness of the first splicing portion 21 is less than that of the first base body 2. Adjacent first base bodies 2 are connected to each other via their respective first splicing portions 21.

[0043] The first sheet 31 and the second sheet 32 ​​can be spliced ​​along the width direction of the first base 2 to form the second base 3, the second base 3 and the first base 2 can be spliced ​​along the width direction of the first base 2, and the second base 3 is installed between two adjacent first bases 2, or the second base 3 is installed between the first base 2 and the column 1.

[0044] The first base 2 , the first sheet 31 and the second sheet 32 ​​are spliced ​​from three directions respectively, thereby forming a complete assembled wall, which is not affected by the column 1 during the assembly process.

[0045] The first base 2 may be an integrally formed prefabricated concrete part, or a color-coated steel plate with a fireproof wool interlayer, or two color-coated steel plates connected by a C-shaped steel.

[0046] The first sheet 31 and the second sheet 32 ​​are made of the same material as the first base 2 , and the second base 3 formed by assembling the two has the same function as the first base 2 .

[0047] In the above technical means, the first splicing portion 21 of the first base 2 close to the column 1 can be protruding outward or recessed inward. For these two situations, first sheets 31 and second sheets 32 of different shapes can be used for splicing therewith, which will be explained through multiple embodiments below.

[0048] in--

[0049] Embodiments 1, 2, 3, and 4 correspond to the working condition where the first joint portion 21 of the first base 2 close to the pillar 1 protrudes outwards;

[0050] Example 5 corresponds to the working condition where the first joint portion 21 of the first base 2 close to the pillar 1 is recessed inwards;

[0051] The sixth embodiment corresponds to the following steps: installing the first sheet 31 and the second sheet 32 ​​in the middle of the assembled wall, that is, at a position away from the columns.

[0052] Example 1, please refer to Figure 3 .

[0053] The first splicing portion 21 of the first base 2 near the column 1 protrudes outward, and the first sheet 31 and the second sheet 32 ​​pass through themselves and the first splicing portion 21 of the first base 2 through the fastener 5 to fix the first sheet 31, the second sheet 32 ​​and the first base 2.

[0054] The fastener 5 is a self-tapping screw.

[0055] In Example 1, the self-tapping screws are exposed on the outside of the prefabricated wall, which is not aesthetically pleasing, and the ends of the first sheet 31 and the second sheet 32 ​​where the self-tapping screws are not installed lack measures to connect each other. Under the action of internal stress, the ends of the first sheet 31 and the second sheet 32 ​​where the self-tapping screws are not installed are prone to warping outward, resulting in gaps and unevenness between the prefabricated wall and the column 1.

[0056] In order to solve the above technical problems, the first sheet 31 and the second sheet 32 ​​need to be connected in a concealed manner, and both ends of the first sheet 31 and the second sheet 32 ​​in the width direction need to be connected.

[0057] Example 2, please refer to Figure 4 .

[0058] The first joint portion 21 of the first base 2 close to the pillar 1 protrudes outward, and the first sheet 31 and the second sheet 32 ​​are connected by a buckle structure 6, which includes a first buckle 61 and a first clamping member 62;

[0059] Two first fasteners 61 are connected to a surface of the first sheet 31 close to the second sheet 32 ​​. The first fasteners 61 are located on both sides of the first sheet 31 in the width direction.

[0060] Two first clamping members 62 are connected to a surface of the second plate 32 close to the first plate 31 . The two first clamping members 62 are respectively engaged with the two first fasteners 61 .

[0061] The first sheet 31 and the second sheet 32 ​​are connected on both sides by two first clamping members 62 and two first fasteners 61 respectively, without any exposed fasteners 5 , thereby preventing warping of both sides.

[0062] In Example 2, the first sheet 31 and the second sheet 32 ​​must be inserted into the first base 2 from both sides of the first base 2 at the same time. Two workers must work simultaneously during assembly, which results in high labor costs.

[0063] In order to solve the above technical problems, it is necessary to enable the first sheet 31 and the second sheet 32 ​​to be independently connected to the first base 2 .

[0064] Example 3, please refer to Figure 5 .

[0065] The first splicing portion 21 of the first base 2 near the column 1 protrudes outward, and the first sheet 31, the second sheet 32 ​​and the first splicing portion 21 are connected by a snap-fit ​​structure 6, which includes a first fastener 61, a first clamping member 62, a second fastener 63 and a second clamping member 64;

[0066] The first splicing portion 21 is connected to one side of the column 1 with two second fasteners 63;

[0067] A first fastener 61 and a second latch 64 are connected to both sides of a side of the first sheet 31 close to the second sheet 32. A first latch 62 and a second latch 64 are connected to both sides of a side of the second sheet 32 ​​close to the first sheet 31. The second latch 64 is located on a side close to the first joint 21.

[0068] When the first sheet 31 and the second sheet 32 ​​are brought closer to each other along the width direction of the first base 2 to form the second base 3 , the first fastener 61 is engaged with the first clamping member 62 , and the two second clamping members 64 are respectively engaged with the two second fasteners 63 .

[0069] In Example 3, the first sheet 31 and the second sheet 32 ​​can be independently connected to the first base 2 through the snap connection of the second clamp 64 and the second fastener 63, so that the two can be installed in sequence without having to be installed at the same time, thereby reducing labor costs.

[0070] In addition to the above embodiment, two fasteners may be installed on one side of the column 1 close to the first base 2 to connect with two clamps on the same side of the first sheet 31 and the second sheet 32 ​​.

[0071] Most of the first splicing parts 21 of the first base 2 do not need to prefabricate the second fastener 63, so prefabricating the second fastener 63 for each first splicing part 21 will increase the production cost. Prefabricating the second fastener 63 for only one first splicing part 21 requires picking the first base 2 during the construction process, increasing the construction cost.

[0072] In order to solve the above technical problem, it is necessary to make the second fastener 63 and the first base 2 separable.

[0073] Example 4, please refer to Figure 6 .

[0074] The first splicing portion 21 of the first base 2 near the column 1 protrudes outward, and the third base 4 is installed between the first base 2 and the second base 3. The side of the third base 4 near the first base 2 is concave inward to splice the first splicing portion 21;

[0075] The first sheet 31, the second sheet 32 ​​and the third base 4 are connected by a snap-fit ​​structure 6, which includes a first fastener 61, a first clamping member 62, a second fastener 63 and a second clamping member 64;

[0076] The third base 4 protrudes outwards toward one side of the pillar 1 and is connected to two second fasteners 63;

[0077] A first fastener 61 and a second latch 64 are connected to both sides of a side of the first sheet 31 close to the second sheet 32. A first latch 62 and a second latch 64 are connected to both sides of a side of the second sheet 32 ​​close to the first sheet 31. The second latch 64 is located on a side close to the first joint 21.

[0078] When the first sheet 31 and the second sheet 32 ​​are brought closer to each other along the width direction of the first base 2 to form the second base 3 , the first fastener 61 is engaged with the first clamping member 62 , and the two second clamping members 64 are respectively engaged with the two second fasteners 63 .

[0079] Example 5, please refer to Figure 7 .

[0080] The first joint portion 21 of the first base 2 near the column 1 is recessed inwards, and a third base 4 is installed between the first base 2 and the second base 3. The third base 4 is embedded in the rectangular cavity formed by the first base 2 and the second base 3.

[0081] The first sheet 31, the second sheet 32 ​​and the third base 4 are connected by a snap-fit ​​structure 6, which includes a first fastener 61, a first clamping member 62, a second fastener 63 and a second clamping member 64;

[0082] The third base 4 protrudes outwards toward one side of the pillar 1 and is connected to two second fasteners 63;

[0083] A first fastener 61 and a second latch 64 are connected to both sides of a side of the first sheet 31 close to the second sheet 32. A first latch 62 and a second latch 64 are connected to both sides of a side of the second sheet 32 ​​close to the first sheet 31. The second latch 64 is located on a side close to the first joint 21.

[0084] When the first sheet 31 and the second sheet 32 ​​are brought closer to each other along the width direction of the first base 2 to form the second base 3 , the first fastener 61 is engaged with the first clamping member 62 , and the two second clamping members 64 are respectively engaged with the two second fasteners 63 .

[0085] Embodiment 4 and embodiment 5 use similar technical means to solve the same technical problem, namely, introducing an intermediary. During transportation, the second base body 3 and the third base body 4 can be pre-assembled into one body and then separated into three parts before assembly.

[0086] The structure of the third base 4 in the accompanying drawings is only an example. It can adopt a square tube, channel steel or other structure, as long as one side of it can be connected to the second fastener 63; when the third base 4 adopts I-beam or C-steel, its own wing plate or flange can replace the second fastener 63, as long as the second clip 64 is designed to be used to hook the wing plate of the I-beam or the flange of the C-steel.

[0087] Example 6, please refer to Figure 8 .

[0088] The second base 3 is installed between two adjacent first bases 2, and the first sheet 31 and the second sheet 32 ​​are connected by a snap-fit ​​structure 6;

[0089] The adjacent surfaces of the two first base bodies 2 that are close to each other protrude outward to form a first splicing portion 21;

[0090] Alternatively, the sides of two adjacent first substrates 2 that are close to each other are recessed inwards, and are embedded with the third substrate 4 to form a first splicing portion 21 that protrudes outwards.

[0091] Optionally, in Examples 2-6:

[0092] The first fastener 61 has an S-shaped cross section. The portion of the first fastener 61 near the first plate 31 protrudes toward the other first fastener 61, while the portion of the first fastener 61 away from the first plate 31 extends toward the other first fastener 61 and away from the first plate 31. The first fastener 61 is elastic.

[0093] The cross section of the first clamp 62 is P-shaped. The first clamp 62 extends in a direction perpendicular to the second sheet 32. The distal end of the first clamp 62 bends toward its proximal end. After the first sheet 31 and the second sheet 32 ​​are spliced ​​together, the first clamp 62 abuts against the first sheet 31.

[0094] Optionally, in Examples 3-6:

[0095] The cross section of the second fastener 63 is C-shaped, and the second fastener 63 is recessed in a direction away from the pillar 1;

[0096] The cross section of the second clamping member 64 is P-shaped. The second clamping member 64 extends in a direction perpendicular to the second sheet 32 ​​. The distal end of the second clamping member 64 bends toward the proximal end thereof. The second clamping member 64 is elastic.

[0097] The two first fasteners 61 respectively form a slot between the first splicing part 21 and the column 1 for the two first clips 62 to be snapped into. In addition to connecting the first piece 31 and the second piece 32 so that the two are difficult to move away from each other, the connecting plate also supports the first piece 31 and the second piece 32 so that the two are difficult to get close to each other.

[0098] The above structure is only an example of the first fastener 61, the first clamp 62, the second fastener 63 and the second clamp 64. It can also be other existing clamping structures 6 structures, as long as it can clamp the first sheet 31, the second sheet 32 ​​and the first splicing part 21, or clamp the first sheet 31, the second sheet 32 ​​and the third base 4.

[0099] It should also be noted that:

[0100] A support member 34 is installed between the first sheet 31 and the second sheet 32. The support member 34 is used to support the first sheet 31 and the second sheet 32 ​​to prevent them from approaching each other. When the first sheet 31 and the second sheet 32 ​​clamp the support member 34, the thickness of the second base 3 is equal to the thickness of the first base 2.

[0101] One of the first fastener 61 and the first clamp 62 is connected to the support member 34 , and the gaps between the first sheet 31 , the second sheet 32 ​​and the support member 34 can be filled with fireproof cotton.

[0102] At least one of the clip and the fastener of the existing buckle is elastic. In the above exemplary structure, the first fastener 61, the first clip 62, the second fastener 63 and the second clip 64 are all springs, that is, elastic metal sheets. The elastic connection between them through the buckle structure 6 itself has the following disadvantages:

[0103] When the thickness of the spring is thin, its elastic force is small, and the first plate 31 and the second plate 32 are easily connected to each other. However, the thin thickness makes the connection between the first plate 31 and the second plate 32 less firm.

[0104] When the thickness of the spring is thick, its elastic force is large, and it is difficult for the construction workers to push the first plate 31 and the second plate 32 to elastically deform the spring, and it is also difficult to engage the first plate 31 and the second plate 32.

[0105] To solve the above technical problems, please refer to Figure 9 .

[0106] In embodiments 2-5, the first fastener 61 is connected to the first plate 31 via an elastic hinge 7;

[0107] In embodiments 3-5, the second clamping member 64 and the second plate 32 are connected via an elastic hinge 7;

[0108] The clamping member and the fastener are both rigid members. During the contact process between the clamping member and the fastener, the support member 34 adaptively rotates through the elastic hinge (8) so that the clamping member and the fastener are engaged with each other.

[0109] The elastic hinge 7 includes a rotating shaft 71, a first connecting portion 72, a second connecting portion 73 and a torsion spring 74;

[0110] The first connecting part 72 and the second connecting part 73 are connected by the rotating shaft 71, and the torsion spring 74 is mounted on the rotating shaft 71. The two ends of the torsion spring 74 are respectively connected to the first connecting part 72 and the second connecting part 73, so that the first connecting part 72 and the second connecting part 73 always have a relative rotation tendency around the rotating shaft 71.

[0111] In embodiments 2-5, the first connecting portion 72 is connected to the first fastener 61 , and the second connecting portion 73 is connected to the first sheet 31 .

[0112] In embodiments 3-5, the first connecting portion 72 is connected to the second clamping member 64 , and the second connecting portion 73 is connected to the second sheet 32 ​​.

[0113] The elastic hinge 7 makes the first fastener 61 and the second clip 64 elastic, and the elasticity is independent of the thickness of the first fastener 61 and the second clip 64, so that the designer can design the first clip 62, the first fastener 61, the second clip 64 and the second fastener 63 into a thicker rigid body to enhance their tensile and compressive properties.

[0114] However, when the elastic force of the elastic hinge 7 is relatively small, the connection between the first sheet 31 and the second sheet 32 ​​in the thickness direction of the first base 2 may still be insufficiently strong. When the torsion spring 74 reaches the end of its service life or the prefabricated wall is affected by an earthquake, there is a risk that the first sheet 31 and the second sheet 32 ​​may separate from each other.

[0115] To solve the above technical problems, please refer to Figure 10 、 11 , providing an elastic hinge 7 that can self-lock when unfolded to a specified angle, even if the torsion spring 74 fails, the angle between the first connecting part 72 and the second connecting part 73 will not change.

[0116] The rotating shaft 71 includes a first stopper 711, a first circular shaft 712, a spline shaft 713, a second circular shaft 714 and a second stopper 715 which are coaxial and sequentially connected;

[0117] The first connecting portion 72 is provided with a coaxial first circular hole 721 and a first spline hole 722. The second connecting portion 73 is provided with a coaxial second circular hole 731 and a second spline hole 732. Along the axis of the rotating shaft 71, the first spline hole 722, the second spline hole 732, the second circular hole 731 and the first circular hole 721 are sequentially provided.

[0118] When the rotating shaft 71 is arranged vertically, the first stopper 711 overlaps the first connecting portion 72 to prevent the rotating shaft 71 from moving downward. The first circular shaft 712 is inserted into the first spline hole 722, the spline shaft 713 is inserted into the second spline hole 732, and the second circular shaft 714 passes through the first circular hole 721 and the second circular hole 731.

[0119] The height of the bottom end of the rotating shaft 71 is lower than the height of the bottom ends of the first piece 31 and the second piece 32. When the first piece 31 and the second piece 32 are placed on the ground, the bottom end of the rotating shaft 71 contacts the ground and is forced to move upward. The second stop member 715 contacts the first connecting part 72 to prevent the rotating shaft 71 from moving upward. At this time, the spline shaft 713 is inserted into the first spline hole 722 and the second spline hole 732 to prevent the relative rotation of the first connecting part 72 and the second connecting part 73.

[0120] The construction workers place the first piece 31 and the second piece 32 on the wooden planks, and then push the first piece 31 and the second piece 32 to engage to form a second base 3 spliced ​​between the first base 2 and the column 1. The wooden planks are then removed, and the second base 3 sits on the ground under the action of gravity. Since the bottom end of the rotating shaft 71 is lower than the bottom end of the second base 3, the rotating shaft 71 is forced to move upward so that the first connecting part 72 and the second connecting part 73 are engaged through the spline shaft 713. Even if the torsion spring 74 fails, the angle between the first connecting part 72 and the second connecting part 73 will not change.

[0121] It should also be noted that:

[0122] The first stopper 711 is an annular flange integrally formed with the first circular shaft 712 , and the second stopper 715 is a nut threadedly connected to the second circular shaft 714 .

[0123] The aperture of the first spline hole 722 at one end close to the spline shaft 713 gradually increases so that the spline shaft 713 can be inserted into the first spline hole 722 when the spline shaft 713 and the first spline hole 722 are not aligned.

[0124] This is to prevent the spline shaft 713 from being inserted into the first spline hole 722 during transportation or construction, causing the elastic hinge 7 to be unable to be unfolded or retracted, so that the first piece 31 and the second piece 32 cannot be connected.

[0125] In order to solve the above technical problem, it is necessary to prevent the second stopper 715 from moving toward the first connecting portion 72 when no external force is applied.

[0126] A brittle sleeve 75 is provided between the first connection portion 72 and the second stopper 715 . The brittle sleeve 75 is used to prevent the second stopper 715 from moving toward the first connection portion 72 . When the second stopper 715 is forced to move toward the first connection portion 72 , the brittle sleeve 75 is broken by the force.

[0127] The brittle sleeve 75 includes two clips 751 and a plastic rod 752 connecting the clips 751. The clips 751 are clamped on the second circular shaft 714. When the second stopper 715 is forced to move toward the first connecting portion 72, the plastic rod 752 breaks brittlely.
